In this Application Report - Grid-Connected Micro Solar Inverter Implement
Using a C2000 MCU (SPRABT0) from TI.
It use SCR full-bridge for inverting instead of using IGBT full-bridge.
The full-bridge SCR switching at line frequency (60Hz). The SCR turn off when the current try to reverse but the voltage on the capacitor on the DC-link won't go to be 0 so I am wondering how it can turn SCR off on accurate time?
